MAGNETIC SEPARATOR.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed May 6,1906. Serial No. 315,327.

To all whom it may concern:

Be it known that I, JAMES CLARENCE WINDER, a resident of East Point, in the county of Fulton and State of Georgia, have .invented 'hertain new and useful Improvements in Magnetic Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in magnetic separators for use with cotton-seed delinters, cotton-gins, dust-fines, and in any placewhere it is desirable to separate magnetic from other substances'such as cotton, cotton-seed, -or non-magnetic metalsthe object of the invention being to improve and simplify such separators and to increase the efficiency ofthe same.

A further object is to so construct the separator as to insure the arrest of such objects as may be cylindrical in shape, and-therefore liable to roll.

A further object is to construct the separator in such manner as to avoid all possibility of fire from overheated electric wires.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims. 1

In the accompanying drawings, Figure 1 is a perspective view showing an application of my improvements. Flg. 2 1s a View showing the side of the separator opposite that which is shown in Fig. ,1. Fig. 3 is a longitudinal sectional view. Fig. 4 is a transverse sectional view.

1 represents a troughv or chute, whlch may be the feed-hopper of a dellnter, cotton-gin, or other machine in the use of which it is desirable to separate magnetic particles or devices from the material being treated, so as to avoid injury to the mechanism, which such particles or devices might otherwise cause. In the application of my lnvention shown in the drawings the se arator is hinged to the side of the trough or opper, so that when it is closed it will form a part of the wall of said trough or hopper and be disposed in operative position to arrest magnetic particles which may attempt to pass to the operating parts of the machine. I

In constructing my improved separator I employ a strip 2, preferab y of wood, having a series of three parallel grooves 3 in one face.

In these grooves bars 4 5 6 of iron or steel are secured, preferably by means'of screws, the heads of the screws lying flush with the exposed faces of the bars. The wooden strip 2 is provided at intervals with openings 7 for the accommodation of electromagnets, each of which is constructed with three poles secured to the respective bars 4 5 6 by means of countersunk screws. In constructing the magnet I employ three iron or steel plates 8 9 10, to be secured, respectively, to the bars 4 5 6 by means of the countersunk screws above referred to, and these plates are separated from each other by means of thimbles 11 of iron or steel. The several plates and the spacing-thimbles are secured togetherby means of a transverse bolt. The spaces between the plates 8 9 10 are occupied by helices 12 13, included in' series with each other and with a suitable source of electric current. The helices are so wound on the thimbles 11 that the two outer plates will be of one polarity and. the intermediate plate 9 of the opposite polarity. In other words, each magnet is made With two salient poles 8 10 and an intermediate consequent ole 9'.

It will therefore be apparent that the are 4 and 6 will be of the same polarity (positive, for instance) and the intermediate bar 5 will be of the opposite or negative polarity. It has been found in practice that with such arrangement of magnetized bars the separator is much more eflicient than, where two bars forming the terminals or pole-pieces of bipolar magnets are employed. With my improved arrangement should a cylindrical object or any device which is liable to roll en age the bars 4 and 5 its progress through t e feedhop or would be promptly checked, and it won (I be positively arrested on bridging the bars 5 and 6.

Several tripolar ma nets, such as above described, may be employed with a single series of bars 4 5 6, according to the length of the separator, the several magnets bein secured to the bars at intervals, and the he ices of all the magnets will preferably be arranged in series with each other and with the source of current. In order to render the magnets easily removable, the helices of one magnet may be connected with the helices of ad aed out in the use of my improved magnet I cent magnets through bindingosts 113, and" these binding-posts are locate on plates 14 ofinsulating and fireproot' material, and the wires leading from theheliees to. the bindingposts are passed through tubes 15, set into the face of the wooden strip 2', in, order to avoid possibility of the wooden strip 2 becoming firom overheated electric conductors.

In addition to the advantage above pointaln enabledto produce etic bars of great ei'ficiency, and the w l'e device is made very compact and powerful:

Various slight changes might be made in the details of construction of my invention- Without departing from the s irit thereof or limiting ilts scope, and hence do not wish to magnet comprising three plates projecting through the slots in the base and secured respectively to said strips, thiimbles separating said: plates helices wound on said; thirnbles to energize the central plate with one polarity and the end; plates with the opposite clarity, and means securing said plates, thim les and helices, together.

2. In a magnetic separator, the combination with a strip or su port having a series of slots and a series of three magnetlc bars disposed upon said striporsupport, ofa series of eleetromagnets progecting through the slots having three poles secured to the respective bars, insulating-bars secured to said strip or support, building-posts secured to said. strip;

Or support, electric conductors between the bindi -posts and the helices of-themagnets, and tu es inclosi'ri saidelectrical conductors.

In testimony w ereof I have signed this specification in the presence of two subscribing witnesses.
